Exchange 2007 Prob
Can receive external email, but cannot send - have set up a Send connector and it is pointing to our Smart Host...
Also got a prob with OWA and ISA using an SSL externally but thats on hold until I can get a bnew CNAME created by our DNS Providers...

have you setup the rule on your ISA box?
Protocols: NNTP / NNTPS / SMTP Server / SMTP
From: Internal / Local Host / (COMPUTER) < You might need to add this if you havent already done so

No joy - still cannot send external email

silly thought but is the router configured properly to forward?
do you get any NDR's?

For outgoing it shouldn't need to.

No, its open...
Not had any NDRs yet - just "Delayed" reports...
Seems odd that i can receive but not send - usually its the other way round!

Right, This is what I need to work on over the weekend
Checked the Message Queue in EMS and seen this:
I can find no reference to "." however...
451 4.4.0 Primary target IP address responded with: "." Attempted failover to alternate host, but that did not succeed. Either there are no alternate
hosts, or delivery failed to all alternate hosts.
At home as caretaker chucked us all out and sodding VPN still isn't working

Where abouts is your smarthost located in relation to your exchange server?
One good test - see if you can telnet to your smarthost (on port 25) from your exchange box. You may also get a more meaningful error message!

I know sorry, My fault wasn't thinking at the time

Make sure you are specifying port 25 as the port - telnet will just default to 23 otherwise

Weird thing is that it was working on my previous setup albeit on Exchange 2003!
Guessing my ISA is a bit pear shaped as cannot get my VPN working either!
I can get out but nothing can in!!

errrrrrrrrrrrrrrrrrrrrrrrr ISA, pile of rubbish

It's beginning to look that way..
What are the benefits for having an Edge Server and where is best to put it? (in or out of the domain?)
